The endostomlal septum does not extend vertically from tlie level 

 of the front to the level of the mouth, except at its posterior limit. 



The crest at the distal end of the arm is fonr-lobed : the upper 

 surface of the wrist and tlie outer surface of the palm have numerous 

 bullous tubercles like those on the carapace : the crest of the palm is 

 serrate. 



The abdomen is as in C. lojplios. 



The sterna corresponding to the 2nd, 3rd and 4th legs are inflated.

The extreme length of the carapace is a little greater than the ex-

 the eyes, the tubercles becoming squamiform posteriorly : the antero- 

 lateral borders crisply crenulate, the posterior border entire and unarmed. 



The clypeiform expansions are slightly developed, and plainly con- 

 sist of about 7 convex carinate teeth fused together except at the tip. 



Pterygostomian region with few scanty hairs. 



Rostrum sharply and deeply bilobed, each lobe being again sub- 

 divided at tip ; projecting well beyond the level of the orbits, and 

 rather broader than them. 



Flagellum of antenna nearly half the length of the carapace. 



Endostomial septum extending vertically from the level of the front 

 to the level of the mouth ; its free edge greatly thickened, its anterior 

 edge sharply excised. 



Crest at the distal end of the arm broadly and faintly fonr-partite : 

 Tipper surface of wrist and outer surface of palm crisply tuberculate : 

 crest of palm sharply serrate.
